Selective door operation is implemented at certain railway stations in the United States. In the New York City Subway, the 6 + 1 ⁄ 2-car-long platforms at 145th Street (and formerly the 5-car-long loop platforms at South Ferry) are too short to accommodate full-length trains of ten 51.4-foot-long (15.7 m) cars, so only the first five cars of the train opened their doors at these stations.

An Advanced Train Control System (ATCS) is a North American system of railroad equipment designed to ensure safety by monitoring locomotive and train locations, providing analysis and reporting, automating track warrants, detecting blind spot and similar orders. [1]
In 1906, the Great Western Railway in the UK developed a system known as "automatic train control". In modern terminology, GWR ATC is classified as an automatic warning system (AWS).

General Railway Signal Company (GRS) was an American manufacturing company located in the Rochester, New York area. GRS was focused on railway signaling equipment, systems and services. The company was established in 1904 and became part of Alstom Transport in 1998.
